AUTOMATIC SWING.

Specification of Letters Patent.

Application filed December 10, 1910.

Patented Apr. 11, 1911.

Serial No. 596,679.

To all whom it may concern:

Be it known that I, LOUIS THEODORE TUR- MELLE, resident of LakeEtchemin, county of Dorchester, Province of Quebec, Dominion of Canada,laborer, having invented certain new and useful Improvements inAutomatic Swings, do hereby declare that the following is a full, clear,and exact description of the same.

The invention relates to improvements in automatic swings, as describedin the present specification and illustrated in the accompanyingdrawings that form part of the same.

The invention consists of the novel construction and arrangement ofparts whereby the oscillation of the swing body is main tained by thecontinuous rotation of the shaft, suitably journaled in the supportingframe.

The objects of the invention are to devise a swing for pleasure resortsand gardens that may be operated safely by children and thoseinexperienced wit-h mechanical and electrical machinery, and to providea simple and reliable mechanism and a safe structure for the purpose.

In the drawings, Figure 1 is a perspec tive view of the structurepartially broken away at the upper end, showing the operating mechanism.Fig. 2 is an end elevation of the swing. Fig. 3 is an enlargedperspective detail of a portion of the frame and a spring pawl. Fig. 4:is a detail of the toothed wheel and its spring connections to the shaftand the pulley mounted on the shaft.

Like numerals of reference indicate cor responding parts in each figure.

Referring to the drawings, 1 are the uprights of inverted V-shaped form.

2 are the cross bars supporting the platform 3.

1 is a rectangular frame supported at the upper end of the uprights land extending beyond said uprights at one side thereof.

5 is a cross beam extending between the side beams of the frame 41 andrigidly secured to one of the uprights 1.

6 is a central longitudinal beam between the cross beam 5 and one of theend beam of the frame 4.

8 is the top beam of the swing having shaft extensions therefromjournaled in the bearings 9.

10 are the vertical side bars of the swing rigidly secured to the topbeam 8 at their upper ends.

11 is a seat firmly secured to thevertical bars 10.

12 is the foot-board secured to the bottom of the vertical bars 10.

13 is a wire secured to the eye 1& at the rear end of the platform 3 atone end and having at the other end the loop 15.

16 is a foot lever pivotally secured to the foot-board 12 toward thefront edge thereof and having a hook projecting therefrom engaging theloop 15 for retaining the seat to its rear position so that on pressingthe said lever 16 with the foot, the looped wire or rope 18 is releasedfrom engagement with the hook 17 and the swing set in motion.

18 are bearings supported on one of the side beams of the frame 1 andthe beam 6 respectively intermediate of the lengths thereof.

19 is a shaft journaled in the bearings 18.

20 is a sleeve mounted on the shaft 19 and having the circumferentialslots 21 there through.

22 is a toothed wheel fixedly mounted on the sleeve 20 between the slots21. r

23 are spiral springs at one end extending through the slots 21 andsecured to the shaft 19 and at the other end secured to the side facesof the wheel 22, intermediate of the distance between the center and theteeth thereof.

241 is a pulley fixedly mounted on the shaft 19 beyond the inner one ofthe bearings 18.

25 is a motor supported on the end beam of the frame 4:.

26 is a pulley mounted on the motor shaft, operatively connected withthe pulley 24 by the belt 27 said transmission of power from the motorto the shaft 19 being designed to impart a comparatively slow motion tosaid shaft 19.

28 is an arm extending laterally from and fixedly secured to the topbeam 8.

29 is a pivoted lever secured to the outer end of the arm 28.

30 is a spring secured to the pivoted lever '29 and the arm 28, andexerting a backward pull on said lever 29.

31 is a guiding plane rigidly secured to the frame 4 and engaged by theback of the head of the lever 29.

32 is a spring-held locking pawl pivotally secured to a strut 7 andnormally engaging the tooth of the wheel 22, said pawl bein releasedfrom engagement with said whee at each upward movement of the pivotedlever 29, said pivoted lever being a releasing lever to permit therotation of the wheel 22 to the extent of one tooth, therefore, at eachforward swing of the seat 11, assaid releasing lever 29 makes an upwardmovement and releases the pawl 32, thus allowing the wheel 22 to rotateand making that rotation intermittent to correspond with the oscillationof the said seat. The pivoted lever 29 has a recess 33 to receive thetooth of the wheel 22, which is released from engagement with the pawl32, consequently as the seat begins to swing baclrwardly, the lever 29moves downwardly, thereby traveling with the rotation of the wheel, thespring pawl returning to engagement with the wheel at the nextsucceeding tooth.

34 is a lever pivotally secured to the cross beam 5 and connected to thestopping and starting mechanism of the motor by the rods 35 and 36respectively.

37 is a cord at its upper end connected to one end of the lever 34 andat its lower end having the handle 38, said cord extending through asuitable hole in the top beam 8.

39 is a cord at its upper end secured to one end of the lever 34 andhaving at its lower end the handle 40, said cord extending through asuitable hole in the cross top beam 8.

The cords 37 and 39 extend downwardly to within easy reach from the seat11, consequently the passenger may readily control the operation of themotor from his position on said swing.

In the operation of the invention, the passenger seats himselfcomfortably and pulls the cord for starting the motor and presses hisfoot on the lever 16, and the seat, being in its extreme rear position,swings forwardly. The pivoted lever 29 slides upwardly, being guided bythe plane 31 to the pawl 32, releasing said pawl from engagement with atooth of the wheel 22. The shaft 19, which is rotating through itsconnection with the motor 25, exerts a pull on the springs 23, thus whenthe tooth is released from the pawl 32, the wheel springs forward to theextent of one tooth, and as the pivoted lever 29 has taken the place ofthe pawl 34, said pivoted lever is forced downwardly and consequentlythe arm 28. The said arm 28 being rigidly connected with the top beam 8,the seat is swung back to its rear position. This operation iscontinuous while the motor is going, as by the continual rotation of theshaft and the prevention of the rotation of the wheel by the pawl 32,the tension of the springs 33 is maintained sufficiently to impart tosaid wheel an intermittent movement and this intermittent movementsecures the backward swing of the seat.

What I claim as my invention is:
